Shop-Made Loose Tenon Jig

This compact, shop-built jig makes cutting accurate mortises with a palm router fast, easy, and repeatable — without the hassle of clamping and realignment for every cut. Designed to function like a biscuit joiner or a Festool Domino, this jig mounts the router to a set of guide rods, allowing smooth, controlled motion in all directions. With adjustable stops and a precision fence, you can dial in consistent mortise locations every time.

Unlike many complex or one-off mortising jigs, this version is built for repeat use across a wide range of projects. It’s ideal for woodworkers looking to simplify loose tenon joinery without investing in expensive machines. The included plans walk you through construction and setup, and even show you how to incorporate the jig into your joinery workflow for dependable, high-quality results.
